(From real4youmarketing@gmail.com) Good day!

I would like to know if you've been seeking professional but cheap web design services. I can make some changes on your site or give it a total makeover, all for a reasonably affordable price! I'm a freelance web designer dedicated in helping businesses like yours grow, and I do this by making sure that your website is the best it can be in terms of the aesthetics, functionality and reliability in handling your business online.

I would like to share my insights about this during a time that's most convenient for you and also let you see my portfolio, so you can be more familiar with the work I've done for my other clients and what the results have been. Please let me know if you're interested, and I'll get in touch with you via the phone. I hope to speak with you soon. 

Priscilla Schwartz

p.s. If you'd like to be excluded from any of my emails, please email me back to inform me and I will remove you from my list. Best Regards.
